BNOWPLOW.

Application filed April 28, 1828. Serial No. 634,103.

To all whom it may concern.

Be it known that I, MARVIN G. LEE, a citizen of the United States, residing at Alliance, in the county of Box Butte and State of Nebraska, have invented a new and useful Snowplow, of which the following is a specification.

This invention aims to provide a simple but efficient means whereby snow may be removed from highways, railroads or other places of travel. and be deposited at one side.

The invention aims to provide novel means for collecting the snow, carrying the snow rearwardly, and then moving it laterally, novel driving connections being provided for the movable parts of the machine.

It within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

\Vith the above and other objects in view, which will appear as the description roreeds. the invention resides in the combination and arrangement of parts and in the de tails of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in slde elevation, a device constructed in accordance with the invention; Figure 2 is a top plan; Figure 3 is a section taken approximately on the line 33 of Figure 2; Figure 4 is a section taken approximately on the line 4-4 of Figure 3.

The structure formin the subject matter of this application is a opted to be carried on a support of any desired sort, the support, in the present instance, being de icted as comprising side beams 1 assemb ed with a motor propelled vehicle 2. A scoop 3 is provided, the scoop being a composite structure and including forwardly diverging side walls 4 and 5 which converge as they extend downwardly. If desired, the walls 4 and 5 may be reinforced, as indicated at 6, to any desired extent. Ordinarily, the side wall 4 of the scoop is secured b means of a bracket 7 to one side beam 1. bottom 8 is formed integrally with or otherwise connected to, the side wall 4 as shown best in Figure 3, the bottom slanting downwardly and forwardly, and being of concaved outline. The

bottom 8 is joined as at 9 in Figure 3 to the side wall 4 of the scoop and is secured as at 11 in Figure 3 to one side beam 1 of the support. The scoop 3 includes a rear wall 12. An arched top 14 is connected at one side to the side wall 4, as indicated in Figure 3, the top, the side walls 4 and 5, the bottom 8 and the rear wall 12 cooperating to form a compartment at the rear end of the scoop 3. Braces 15 diverge from the side beams 1 and 1t) and are connected at their forward ends to the side walls 4 and 5 of the scoop 3. A suction and blower casing 17 is connected at.

18 to the side beam 10, one edge of the top 14 being secured at 20 to the casing 17. The compartment which exists beneath the top 14 communicates as at 19 in Figure 3 with the casing 17. The casing 17 carries an upwardly extended stack 21 whereon a laterally projecting cowl 22 is journahxl for adjustment, the cowl having a rack 23 adapted to be engaged by a latch 24 on the stack 21.

There is a bearing 25 on one side beam 1, the casing 17 having a bearing 26. and in the bearings, a main shaft 27 is journaled. the shaft 27 extending transversely of the machine and carrying fan blades 28 operating in the casing 17. A feed screw 29 is carried by the main shaft 27 and operates in the compartment which exists beneath the top 14 of the scoop 3. A frame 30 connects the side beam 1 and the side beam 10 and carries a forwardly presented bearing 31, showing in Figure 2. There are bearings 32 on the bottom 8 of the scoop 3, as Figure 2 will show. In the bearings 31 and 32 are journaled downwardly inclined, forwardly diverging shafts 33, passing through the rear wall 12 of the scoop 3 and carrying worms 34 located between the side walls 4 and 5 of the scoop and above the bottom 8. Beveled gears 35 are secured to the rear ends of the shafts 33 and mesh with each other.

An internal combustion engine 36 is mounted on the frame of the vehicle 2 and is located at any desired point to the rear of the forward wheels so as to counterbalance the weight of the snow plow mechanism. The shaft of the internal combustion engine 36 is marked by the numeral 37 and carries a sprocket wheel 38 about which is trained a. sprocket chain 39 engaged with a sprocket chain wheel 40 on the shaft 27 which 0 crates the transverse worm 29. The sha 27 is provided with a worm 41 Cit (Figure 2) meshing with a. worm wheel 42 (Figure 3) on a shaft 43, extended longitudinally of the frame and journaled 1n a bearing 44 on the member 1. A shaft 45 extends transversely of the line of advance of the vehicle and is journaled in a bearing 46 on the frame member 1, and in a bearing 47 on the part 3 Intermeshing beveled pinions 48 establish connection between the shaft 45 and the shaft 43. A beveled pinion 49 on the inner end of the shaft 45 meshes with one of the beveled pinions 35 on the shafts 33.

In practical operation, the snow is received between the side walls 4 and 5 and is carried. transversely of the line of advance of the vehicle, toward the median plane of the vehicle, the snow moving rearwardly and coming into the field of the arms or angers 34 which break up the snow and carry it backwardly and upwardly along the inclined bottom 8 of the scoop. The snow is engaged by the transverse feed screw or, p

auger 29 and is moved through the openin' 19 into the casing 17 of the suction fan and blower, the snow being discharged by the blades 28 through the stack 21 and the cowl 22. By disengaging the latch 24 from the rack 23, the cowl 22 may be so positioned as to discharge the snow in any desired direction.

From the shaft 37 of the engine 36, motion is transmitted by the sprocket wheel 38, the sprocket chain 39 and the sprocket wheel 40 to the shaft 37, the shaft 27 operating the transverse auger 29 and the fan blades 28. The worm 41 and the worm wheel 42 rotate the shaft 43, and from the shaft 43 motion is transmitted to the shaft 45 by the intermeshing beveled pinions 48, the beveled pinion 49 on the inner end of the shaft 45 rotating one of the beveled pinions 35, the beveled pinions 35 coacting to'impart rotation to the shafts 33 and to the angers 34.

What is claimed is v 1. A snow plow comprising a support; a scoop carried thereby; a Suction and blower mechanism located at one side of the scoop and communicating therewith; a first conveyor operating longitudinally of the scoop; a second conveyor operating transversely of the scoop and receiving material from the first conveyor, the second conveyor discharging into the suction and blower mechanism; and means for operating the conveyors.

- 2. A snow plow comprising a support; a scoop carried thereby; a suction and blower mechanism communicating with the scoop; a first worm conveyor operating longitudinally of the scoop; a second worm conveyor operating transversely of the scoop and receiving material from the first worm eonyeyor, the second worm conveyor discharglng into the suction and blower mechanism; and means for operating the worm conveyors.

3. A snow plow comprising a support; a scoop carried thereby; a suction and blower mechanism comprising blades; a shaft suported for rotation; a worm conveyor carried by the shaft and operating in the scoop, the worm conveyor dlscharging upon the blades, and the blades being carried by the shaft; and means for driving the shaft.

4. A snow plow comprising a support; a scoop carried thereby; a main shaft extended transversely of the scoop; a worm conveyor carried by the main shaft, another worm conveyor extended longitudinally of the scoop; a supplemental shaft disposed transversely of the support; intermeshing beveled pinions on the supplemental shaft and on the last specified worm conveyor; means for connecting the shafts; an engine on the support; and means for connecting the engine operatively with one shaft.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

MARVIN G. LEE.
